Comparision of the Cannon, Tamron & Sigma 70-200mm out.
Cannon still unbeatable.
In chinese.

from what I understand here

at 70mm, the tamron is sharpest at center and corner wide open.
at 135mm and 200m, canon is overall winner but tamron is not that far off, with sigma being the softest.
given double the price tag, it is no surprise to see canon still comes out top.
Then again, at 1/2 the price, and having at least 85% performance of the canon L glass, it's already a steal. Not to mention it's lighter, and has closest min. focusing distance too yumm
